Perfect Squares and Square Roots

Numbers and Algebra

This video investigates and uses square roots of perfect square numbers to create and solve equations. Viewers will learn how to determine the square roots of perfect squares, and determine if a number is a perfect square using technology and factor trees. Step by step graphics, ideal for reinforcing concepts.

Survey Data: Collecting and Displaying

In this clip, the results of student surveys are collated into tables and means are calculated. Students are asked to rate a music genre from 1 to 5, and in a separate survey, are asked to identify their favourite genre from a given list. This resource explores categorical and numerical data, relative frequency, sample size, variation of means, and column graph interpretation.

Line Graphs: Gradients and Midpoints

Numbers and Algebra

This video follows a sprinter graphing her distance and speed for two separate sprints. Follow along as she determines gradients and midpoints and her average speeds for both sprints as well as her speeds at different intervals. This is an excellent resource for applying mathematical concepts to real world situations.
